Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655732, here are decompositions:

11 + 8655721 = 8655732
13 + 8655719 = 8655732
31 + 8655701 = 8655732
53 + 8655679 = 8655732
61 + 8655671 = 8655732
79 + 8655653 = 8655732
83 + 8655649 = 8655732
101 + 8655631 = 8655732

Showing the first eight; more decompositions exist.
